BENDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 456,774, dated July 28,1891. i 7

Application filed October 4, 1890. $erialN0. 36 7,098. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES H. PETERS, a citizen of the United States,residing at Coleman, county of Midland, State of Michigan, have inventeda certain new and useful Improvement in Bending-Machines; and I declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

'lhisinvention has for its object to provide a novel, simple, andefficient machine by means of which the veneers orsheets from which thehead-linings for barrels an d the like are made may be curved or bent ina circular shape. To accomplish this object my invention involves thefeatures of construction and the combination or arrangement of deviceshereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure 1 is a side elevationillustrating the mechanism. Fig 2 is a plan View; and Fig. 3 is avertical section of a part, showing the principle of operation.

In carrying out the invention,A represents a suitable receptacle inwhich the sheets or veneers B are placed,the bottom of the receptaclebeing open and its sides terminating a short distance from the table C.

D is a belt passing over the pulley E, pulley F, and pulley G.

H is a suitable tightener bymeans of which the belt is always kept tightupon the pulley.

.I is a roller around which the belt passes, and the said roller isprovided with longitudinal, corrugations J, which suliiciently fastenupon the sheets of veneer to aid in throwing them over'into thereceptacle.

J is a small roller located beneath the belt between the roller J andthe box A and adapted to support the belt against the downward pressureof the rear end of a sheet of veneer as it passes between the roller andthe belt.

L is a slide upon the table 0 and provided with the handle L.

The operation is as follows: The veneers are placed in the receptacle A,the bottom one resting upon the table. The slide is pushed forward andforces either one or two of the veneers (depending upon the spacebetween the sides of the receptacle and the table) forward until theyare caught between the belt and the roller J. They are then carriedalong between the roller and belt, and there being a uniform pressureupon the whole of the veneer it is uniformly bent throughout its width.When it reaches the upper side of the roller, it is carried over by thelatter and deposited in the receptacle K, from whence it is removed bythe operator to undergo the next step. As before stated, the veneerreturns to substantially its flat position after being thrown out by theroller J, and yet the grain of the veneer has throughout the entirewidth been uniformly strained or bent, so that when it is desired toagain bend the veneer it will respond much more easily and much moreuniformly than had it not been passed through the machine justdescribed. v p

It is obvious that any suitable belt may be used, and that it may bepassed over any desired arrangement of pulleys, the essential featurebeing that the belt shall closely hug a suitable roller for a greaterdistance than the width of the veneer, whereby the veneer shall have auniform pressure throughout its entire width in bending it.

What I claim is In aveneer-bending machine provided with a suitableroller, and a belt passing over and closely hugging said roller, a table0 adjacent to the said roller, a receptacle A upon the table, a slide Lbeneath the receptacle, and a delivery-box K, adapted to receive thebent sheets of veneers, all arranged substantially as and for thepurposes described.

In testimony whereof I sign this specification in the presence of twowitnesses.

JAMES H. PETERS.
